2024年12月3日 · Polyvinyl alcohol (PVA) is a non-toxic, biodegradable polymer that has a wide range of applications. It is synthesized from ethylene, oxygen, and acetic acid.

Polyvinyl alcohol (PVA) is a synthetic polymer characterized by its repeating vinyl alcohol units. It’s synthesized through the hydrolysis of polyvinyl acetate, a process that converts acetate groups into hydroxyl groups. This gives PVA its notable solubility in water, a trait not common in many synthetic polymers.
